The word matrix can be used to describe things shaped In a pattern of lines and spaces. How does this relate to a mitochondrion?
Answers
The definition of the word matrix can be applied to the organelle known as mitochondria given that the mitochondria have what is known as a "mitochondrial matrix".
The mitochondria are amongst the most important organelle of a cell. They are responsible for the production of energy molecules in the form of ATP. The basic structure of mitochondria consist of:
Outer membraneIntermembrane spaceInner membrane MatrixGranulesand contain even more elements within.
The inner membrane of the mitochondria surrounds the matrix, giving it the form of a pattern of lines that bend and curve, leaving spaces in between. The similarity between this shape and the definition that is given of the word "matrix", explains why this structure may have been given the name of the mitochondrial matrix.

Diabetes is a disease where the body is unable to produce enough insulin in the pancreas to help lower the levels of blood glucose. The ribosomes manufacturer the insulin in healthy cells, but those who are diabetic do not have healthy cells to do this. In which organ would you find the ribosomes producing insulin in a non diabetic individual?
A.) liver
B.) pancreas
C.) stomach
D.) thyroid
Answers
insulin is produced in the pancreas
The pancreas is the organ in which ribosomes produce insulin in a non-diabetic individual. So, the correct option is B.
What do you mean by Diabetes?Diabetes may be defined as a disease that increases the blood glucose level as compared to normal. This is due to the body being unable to produce enough insulin in the pancreas to help lower the levels of blood glucose.
Insulin is produced in the pancreas with the help of ribosomes in non-diabetic individuals.
Therefore, the organ in which ribosomes produce insulin in a non-diabetic individual is the pancreas.

he valve presents at the mouth of the pulmonary artery
Answers
Explanation:
The pulmonary valve (sometimes referred to as the pulmonic valve) is a valve of the heart that lies between the right ventricle and the pulmonary artery and has three cusps. It is one of the four valves of the heart and one of the two semilunar valves, the other being the aortic valve. Similar to the aortic valve, the pulmonary valve opens in ventricular systole, when the pressure in the right ventricle rises above the pressure in the pulmonary artery. At the end of ventricular systole, when the pressure in the right ventricle falls rapidly, the pressure in the pulmonary artery will close the pulmonary valve.

Which cell type undergoes terminal differentiation?
Answers
Stem cells are the only form of cell that can differentiate into more specialized cell types. Therefore, they undergo terminal differentiation.
What is terminal differentiation?As cells migrate to the surface and fully differentiate, i.e., as they keratinize and eventually die, this process is known as terminal differentiation. Terminal differentiation is a method of describing that the cells change their phenotypic traits.
During the process of terminal differentiation, several cell types (such as neurons, skeletal and cardiac myocytes, adipocytes, and keratinocytes) acquire specific tasks and ultimately exit the cell cycle. This process may be observed in neurons, adipocytes, and keratinocytes.

How are COASTAL ECOSYSTEMS a major source of Oxygen for the rest of Earth’s water??!
Please don’t copy off internet!
Answers
Coastal ecosystems gives aprox. 50% of the earth's oxygen. This is due to the variety of plants that live in their water, example of these are phytoplankton and algae
The coastal ecosystem is a major source of oxygen, because of the presence of plankton, plants, algae, and bacteria that can perform photosynthesize.
What is a coastal ecosystem?A coastal ecosystem is the marine coastal ecosystem. It is the ecosystem where area and the land meet. It includes marine habitats, marine animals, mangroves, algae, backwater, etc.
The coastal ecosystem constitutes 50 to 80% of the earth's oxygen because of the presence of organisms in the region.
Thus, because of the existence of plankton, plants, algae, and bacteria that can photosynthesize, the coastal ecosystem provides a significant source of oxygen.

why are they assuming the large molecules will stay on their own side of the membrane?
Answers
Answer:
What is osmosis? Why are they assuming the large molecules will stay on their own side of the membrane? The membrane is semipermeable, so the membrane only allows some molecules through and not others. In this case, it doesn't allow the large molecules through.
Explanation:
Hope It Helps
It is assumed that the large molecules will stay on their own side of the cell membrane because the membrane is semipermeable which only allows the passage of some molecules in and out of the membrane.
What is a Cell membrane?A cell membrane may be defined as a type of biological membrane that significantly separates and protects the inner environment of all cells from the outside environment. It is semi-permeable in nature.
The cell membrane consists of a lipid bilayer that is semi-permeable. The cell membrane regulates the transport of materials entering and exiting the cell.
The ability of a molecule to travel across a membrane depends on its concentration, charge, and size. In general, molecules diffuse across membranes from areas of high concentration to low concentration. Cell membranes prevent charged molecules from entering the cell unless the cell maintains an electrical potential.
